(Left side) $6ppd KissaLuvs Hybrid one-size contoured: 90% cotton/10% polyester, fits 7-35 pounds.
Purchased this new, still VGUC, just pilly, elastic good. Also, I altered it originally by adding snaps, and then decided it was too much of a pain to do the snaps, and sewed velcro on top. So you don't need snappis to put it together, yay. Oh, and I sewed on a stay-dry layer on top of the sewn-in doubler, double yay.

GONE BELOW $7ppd Motherease Sandy's, I could be wrong because I can't remember, but these are supposed to be one-size, though it fits on DD like a small at the legs.
Side-snapping, made of terry cloth with sew-in inner terry wet zone layer. I inherited this new, still in EUC, snaps all work still, elastic still taut, no stains.

2 Bamboo/silk, one-size $5ppd each Don't know brand, tags cut off, purchased new from BabySteals a year ago and they're in VGUC.
Left shows it snapped up at larger setting; right shows it snapped up at smaller setting. I then added velcro because snaps annoyed me, but took them off for selling purposes, but you'll see an outline of where the velcro was sewed on to. The elastic is pretty worn, which is why they're selling uber cheap.
